CVE-2025-24111 is a memory corruption vulnerability identified in Apple visionOS and several other Apple operating systems including macOS Sequoia 15.3, visionOS 2.3, iPadOS 17.7.7, watchOS 11.3, macOS Sonoma 14.7.5, iOS 18.3, tvOS 18.3, and macOS Ventura 13.7.5. The root cause is improper state management leading to memory corruption, which can be triggered by a local application with limited privileges. This flaw allows the app to cause unexpected system termination, effectively a denial-of-service condition, by crashing the operating system. The vulnerability is classified under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer). The CVSS v3.1 base score is 5.5, indicating medium severity, with the vector AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H, meaning local attack vector, low attack complexity, requires low privileges, no user interaction, unchanged scope, no confidentiality or integrity impact, but high impact on availability. No known exploits have been reported in the wild as of the publication date. Apple has fixed the issue by improving state management in the affected OS versions. This vulnerability primarily threatens system availability and stability rather than data confidentiality or integrity.

For European organizations, the primary impact of CVE-2025-24111 is the potential for denial-of-service conditions on devices running affected Apple operating systems, including visionOS. This could disrupt business operations, especially in environments relying on Apple hardware for critical workflows or emerging visionOS applications. The vulnerability does not allow data theft or modification but can cause system crashes, leading to downtime and potential loss of productivity. Organizations in sectors such as technology, media, and creative industries that adopt visionOS or other Apple platforms extensively may face operational interruptions. Additionally, critical infrastructure or public sector entities using Apple devices could experience service disruptions. The requirement for local access and low privileges limits remote exploitation risks but does not eliminate insider threat or malware scenarios where a compromised app could trigger the crash. Overall, the impact is moderate but significant enough to warrant prompt remediation to maintain system availability and reliability.

European organizations should prioritize deploying the Apple security updates that address CVE-2025-24111 across all affected devices, including visionOS, macOS, iPadOS, watchOS, iOS, and tvOS versions listed by Apple. Beyond patching, organizations should implement strict application control policies to limit installation and execution of untrusted or unnecessary apps, reducing the risk of malicious or buggy apps triggering the vulnerability. Employ endpoint detection and response (EDR) solutions capable of monitoring for abnormal app behavior or frequent system crashes to detect exploitation attempts early. Conduct regular audits of device inventories to ensure all Apple devices are updated promptly. For environments deploying visionOS in particular, establish robust app vetting and sandboxing procedures to minimize the risk of local apps causing system instability. Additionally, educate users and administrators about the importance of applying updates and recognizing signs of system instability that may indicate exploitation attempts. Network segmentation and limiting local access to critical Apple devices can further reduce exposure to this vulnerability.
